The

pull cord unit

30 is made up of a right and a

left pull cords

31, 32, a central pull cord 33, a main pull cord 34, and a locating piece 35. When the fabric drapery 20 is fully unfolded and extended downwards, the right pull cord 31 is attached at one end to the locating piece 35 suspending beneath the main driving means 11 and then reserved for a preset extra length before passed through the main driving means 11 and the first and the second sub-driving means 12, 13 respectively and led through the right hanging rings 212 to be attached to the tubular hole 22 at the other end thereof The central pull cord 33 is attached at one end to the locating piece 35 thereof before passed through the main driving means 11 and the first sub-driving means 12 respectively and led downwards through the central hanging rings 211 to be attached at the other end to a bottom ring 24 disposed at the bottom tubular hole 23 thereof The left pull cord 32 is attached at one end to the locating piece 35 and then reserved for a preset extra length before led through the main driving means 11 and extended downwards to pass through the left hanging rings 212 and attach to the tubular hole 22 at the other end thereof The main pull cord 34 is attached to the bottom of the locating piece 35 thereof and extended downwards for a proper length.

conventional fabric drapery

20 thereof, the locating piece 35 is pulled downwards via the main pull cord 35 to draw up first the lower section of the fabric drapery 20 via the central pull cord 33 with both left and right bottom rods 231 suspending downwards, figuring out a fan-like pattern at the bottom thereof. When the preset extra length thereof are fully stretched downwards, the right and

left pull cords

31, 32 will raise up the elongated rod 221 levelly to fold up the upper section of the fabric drapery 20 orderly via the folding lines 211 thereof to complete the withdrawal of the fabric drapery 20 thereof.

There are some drawbacks to such

conventional drapery fabric

20. First, the pull cord unit 30 made up of the right and

left pull cords

31, 32 and the central pull cord 33 is adapted to the main driving means 11 and the first and second sub-driving means 12, 13, which is quite complicated in assembly. Second, central hanging rings 211, and left and right hanging rings 212 are disposed at the center and the upper lateral sides of the fabric drapery 20 thereof, which are tedious and time-consuming in production. Third, preset extra length of the right and

left pull cords

31, 32 are reserved for complete withdrawal of fabric drapery 20 thereof, which uneconomically boost the cost of materials and production thereof.

SUMMARY OF THE PRESENT INVENTION

It is, therefore, the primary purpose of the present invention to provide a pattern variable fabric drapery, comprising an upper beam with a double-layered fabric drapery attached thereto wherein the upper section of the double-layered fabric drapery has a plurality of elongated tubular holes disposed thereon for long rods to be adapted therein, and the lower section thereof has a plurality of symmetrical left and right tubular holes disposed thereon for left and right elongated rods to be adapted therein respectively. The fabric drapery thereof also has a plurality of left and right hanging pieces with hanging rings, and central hanging pieces with cord-passage rings seamed into a Y-shaped pattern thereon, matching to a left and a right pull cords; whereby, via the left and right pull cords without any preset extra length reserved, the fabric drapery thereof is easily unfold or quickly withdrawn, economically simplifying the process of assembly and reducing the costs of materials as well as production thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 3. The present invention is related to a pattern variable fabric drapery, comprising an [0012] upper beam 40 with a double-layered fabric drapery 50 attached thereto. The upper section of the double-layered fabric drapery 50 is provided with a plurality of elongated tubular holes 51 equidistantly distributed thereon, each formed by an upper and a lower seaming lines 511, 512 for a long rod 513 to be adapted therein. The lower section of the double-layered fabric drapery 50 has a plurality of symmetrical left and right tubular holes 52 equidistantly arranged thereon, each pair thereof formed by an upper and a lower sewing lines 521, 522 and sealed up in the middle thereof for a pair of left and right elongated rods 523 to be adapted therein respectively. Both outer sides of the elongated tubular holes 51 and the left and right tubular holes 52 thereof are sealed up for location of the long rods 513 and the left and right elongated rods 523 thereof respectively. A plurality of left and right hanging pieces 514 each with a hanging ring 5141 attached thereto are symmetrically seamed into a V-shaped pattern at the upper seaming lines 511 of the elongated tubular holes 51 thereof, while a plurality of central hanging pieces 524 each with a cord-passage ring 5241 attached thereto are vertically disposed at the center of the upper sewing lines 521 of the left and right tubular holes 52, matching to the left and right hanging pieces 514 thereof to form a Y-shaped pattern at the fabric drapery 50 thereon.
A driving means [0013] 41 is disposed at one side of the upper beam 40 thereof for a left and a right pull cords 42, 43 to be adapted thereto. One end of the left and right pull cords 42, 43 are passed through the hanging rings 5141 of the left and right hanging pieces 514 respectively to come down together through the cord-passage rings 5241 of the central hanging pieces 524 and be tied up respectively to the last cord-passage ring 5241 disposed at the bottom of the fabric drapery 50 thereof. The other end of the left and right pull cords 42, 43, are led through the driving means 41 thereof to extend downwards thereof at one side of the fabric drapery 50 thereof.
Please refer to FIGS. 4, 5. To gather up the [0014] fabric drapery 50 thereof, the left and right pull cords 42, 43 suspending under the driving means 41 of the upper beam 40 thereof are pulled downwards to withdraw the left and right pull cords 42, 43, led through the left and right banging pieces 514 thereof and the central hanging pieces 524 thereof and fold up the fabric drapery 50 therewith. In a half-drawn stage of the fabric drapery 50, the left and right pull cords 42, 43 thereof are half drawn downwards to gather up the lower section of the fabric drapery 50 by the central hanging pieces 524 thereof with the left and the right elongated rods 523 suspending downwards at both sides thereof, variably figuring out a fan-like pattern at the bottom thereof as shown in FIG. 4. To fully gather up the fabric drapery 50, the left and right pull cords 42, 43 are fully drawn to the end to gather up the lower section of the fabric drapery 50 thereof in a fan-like shape, and then fold up the upper section of the fabric drapery 50 orderly via the long rods 513 raised levelly upwards by the withdrawn left and right pull cords 42, 43 thereof as shown in FIG. 5. Thus, via the left and right hanging pieces 514 and central hanging pieces 524 seamed into a Y-shaped pattern matching to the left and right pull cords 42, 43 without any preset extra length reserved, the fabric drapery 50 thereof is easily unfold or variably withdrawn, economically simplifying the process of assembly and reducing the costs of materials and production thereof.
